In addition, two of the British installations and one Norwegian were linked together by bridges. That made it difficult to determine who was employed on which side. Most people worked on both sectors. Personnel on the free-standing platforms also commuted between the sides. Elf deducted Norwegian tax from everyone, which amounted to a lot more than British tax. Foreigners working in the UK had 50 per cent of their pay exempted from taxation, which amounted to many thousands of kroner for Frigg personnel. Under the new treaty, everyone working on the British side of the field was liable to UK tax.
After a good deal of discussion, Elf and the unions reached agreement that everyone who had the opportunity to do so would alternate between the various platforms. This allowed as many as possible to benefit from the lower British tax rate. The most normal arrangement involved spending two-thirds of the time on the UK side and one-third on the Norwegian.The second oil crisisPig receiver explodes
